BACKGROUND OF THE INVENTION l. Field of the Invention The inventionrelates to tilting double hung windows and refers more specifically to atilting double hung window having a single plastic guide member betweenthe window sash and window frame at each side thereof for providingcompression, Weatherstripping, and sash guiding functions, a two-partcamming and locking structure for pivotally mounting the sash withrespect to the guide member and window frame, unique glazing and mullionstructure and packing clip structure for maintaining the window framedimensions during shipment and installation.

2. Description of the Prior Art In the past tilting double hung windowsof the type which may be cleaned from the inside of a building in whichthe window is installed by pivoting the window sash about one edgethereof to expose the outside surface for cleaning have been deficientin that the usual means for supporting the sash in the window frameshave been rather complicated, often expensive, and sometimesinefficient. Thus, a minimum of three separate members, that is a metalguide for the sash, spring means operable between the window guide andmetal frame for maintaining compression of the metal guide against thesash, and a felt member or similar weatherstrip material between thesash and outer frame have usually been required at each side of thewindow sash.

Wherein locking structure has been provided in the past to maintain thesash of tilting double hung windows in a predetermined vertical positionwhen tilted, the locking structure has been complicated, expensive tomanufacture or inefficient. Further, the prior locking structures havenot generally been readily engageable with and releasable from assemblywith counterbalance structure for the sash.

Similarly, in the past, window sash have sometimes not been capable ofbeing reglazed readily and where glazing has been possible, reglazing ofa window sash has required considerable skill and special tools andmaterial. Sealing between two adjacent windows has also been ratherhaphazard in the past, often amounting to merely packing calkingmaterial between the adjacent windows and providing flanges or the liketo hide the calking material.

Again, in prior window structures wherein a sash is placed in a framefor shipment to and installing on a job site, the frames often becomebowed or warped out of shape in storage, shipment or in installing, sothat the finished window in place has in the past often been difficultto operate due to irregularities in the frame. Correction of theirregularities on the job site again requires considerable skill and istime consuming and therefore expensive.

In addition, prior window structures have generally been either metal orwood, that is, if a metal exterior has been required in the past formaintenance purposes, the interior of previous window structures hasgenerally also been metal. Conversely, when a wooden window has beendesired for aesthetic appearance and warmth, the entire window hasusually been constructed of wood in the past. The interior aestheticappearance and warmth of wood window structure has not previously beensatisfactorily, combined with the maintenance advantages of metalexterior window structure.

SUMMARY OF THE INVENTION The invention is a tilting double hung windowstructure wherein a single plastic guide member is inserted in the frameat each side of the jambs and serves the multiple purposes of providingrequired compression between the frame and sash to maintain the sash inadjusted positions, guiding the sash in vertical movement andWeatherstripping between the sash and frame. The guide members inconjunction with unique two-part camming and locking structure furtherpermit tilting of the sash into substantially any desired position withrelative ease to facilitate cleaning of the window. The window structureof the invention uses a minimum number of separate parts which parts areuniform where possible and are metal on the exterior and wood on theinterior to provide weather resistance and aesthetic appearance.

The sash of the double hung window structure of the invention arereglazable to which end there is provided a unique single piece glazingmember. In addition, the window structure of the invention may beinstalled side by side by use of a single, particularly efficientmullion strip. Further, the installation of the window structure isfacilitated by the provision of packing and shipping clips during themanufacture of the window which maintain the frame dimensions withrespect to the sash during storage, shipment and installation to preventinstallation of the window with the frame deformed so as to hinderoperation of the sash in the installed frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT The window structure 10 of theinvention includes a window frame 12, a pair of window sash 14 and 16and guide members 18 and 20. The frame 12 is metal, the sash 14 and 16are wood, and the guide members 18 and 20 are plastic. The frame, sashand guide members when assembled, as illustrated in FIGS. 3 and 4,provide a tilting double hung window, the sash of which may be pivotedinwardly for cleaning or for subsequent tilting and removing as desired.In addition, as shown best in FIGS. 3 and 4, the window structure 10combines the advantages of a metal exterior and a wood interior so thatmaintenance is kept at a minimum and the natural beauty of wood ispreserved.

More specifically, the frame 12 includes the head member 22, the jambmembers 24 and 26 and the sill member 28. The head and jamb members havea single cross section, as illustrated, including a mounting flange 30to aid in installation of the window structure 10 in a building opening,an exterior molding portion 32 and portions 34, 36, 38 and 40 formingpockets 42 and 44 for receiving the guide members 18 and 20.

The sill member 28 includes the outwardly and downwardly inclinedportion 46 and the portion 48 for securing the sill in a buildingopening. A water-stop portion 50 is provided on the cross section of thesill 48 and a molding receiving portion and sash stop member 52 isprovided on the inside of the sill member 28. The head, jamb and sillmembers 22, 24 and 26 and 28, as shown, may be mitered and connected byconvenient corner structure (not shown).

The sash 14 and 16 are exactly the same and each includes head, jamb andsill members 54, S6, 58 and 60. The head, jamb and sill members areprovided with recesses 62 in which glass panes or other building panels64 are secured by means of the glazing member 66, as shown best in FIG.5, in the case of single thickness glass panes. Insulated window panes68 may also be secured in the recesses 62 in the sash, as shown in FIG.3, by means of a glazing structure 70.

The glazing strip 66 is shown in more detail in FIG. 5 and has agenerally U-shaped cross section with one leg longer than the other. Thelonger leg terminates in a pointed portion 68 extending outwardly fromthe longer leg of the cross section and away from the shorter leg of thecross section. The terminal portion 70 of the shorter leg of the crosssection of the glazing strip 66 extends at an acute angle to the shorterleg toward the connecting portion of the U-shaped cross section and awayfrom the longer leg thereof, again as shown in FIG. 5. The connectingportion of the U-shaped cross section of the glazing strip 66terminates, on the longer leg side of the cross section in a pointedportion 72 and extends outwardly of the U-shaped cross section from theshorter leg in a portion 74, again as shown in FIG. 5.

The particular cross section of the glazing strip 66 permits glazing ofthe sash 14 and 16 with glass panes or similar building panels havingsubstantially varying thickness. Thus, the pointed portions 68 and 72provide excellent weather-seals, the portion 70 is flexible toaccommodate panels of different thickness and further provides a sealingfunction, while the portion 74 of the cross section of the glazing stripprovides a tinished appearance, even with building panels ofconsiderably different thickness.

In use, as will be seen subsequently, the sill of the sash 14 and 16 issecured in place by means of screws passing through the camming andlocking structure illustrated in FIGS. 6 through 9. Thus, in reglazingthe sash 14 and 16, it is merely necessary to remove the glazing strips66, remove the sill of the sash, place a new pane of glass in therecesses 62, replace the sill and press the glazing strip 66 intoposition around the sash in the recesses 62, as shown in FIG. 5.

At the bottom of both the sash member 14 and the sash member 16, asshown in FIG. 6, the camming and locking structure 76, which is bestshown in FIG. 9, is provided to permit pivoting the sash relative to theguide members 18 and 20 and the frame 12.

The camming and locking structure 76 includes the separate cammingmember 78 and locking member 80. The camming member 78 is secured to thesill of the sash, as shown in FIG. 6, by the portions 82 and 84 whichare positioned a substantial distance apart on the base portion 86 ofthe camming member 78 and are adapted to be driven into the sills in theposition shown in FIG. 6. The cylindrical portion 88 of the cammingmember 78 of the camming and locking structure is provided to reactagainst a portion of the guide members as shown in FIG. 8, on tilting ofthe sash to which it is secured. The opening 90 is provided in the otherend of the cylindrical portion 88 of the camming member 78 to receivethe mounting screw 92 by which the locking member of the camming andlocking structure 76 is secured to the camming member 78, the cammingand locking structure 76 is secured to the sash and the sill of the sashis secured to the jambs thereof.

The locking member 80 of the camming and locking structure 76, as shownin FIG. 9, is an elongated member having an opening 94 in one endthereof with an outer enlarged diameter for receiving the head of thescrew 92 and a reduced inner diameter fitting over the bearing portion96 of the cylindrical portion 88 of the camming member 78, whereby thelocking member 80 is pivoted to the camming member 78. The cylindricalextension 98 of the locking member 80 permits ready connection of thecamming and locking structure to the window counterbalance structure100, as shown in FIG. 6, by means of the hook 102 which may be readilyengaged and disengaged therefrom should it be desired to remove the sash14 or 16 from the frame 12. Serrated edges 104 are provided on thelocking member 80 of the camming and locking structure 76, whereby ontilting of the sash, as shown in FIG. 8, so that the camming member 78engages one portion of the guide strips, the serrations are forced intoengagement with an adjacent portion to lock the sash in a predeterminedvertical position during tilting thereof.

The guide members 18 and 20 are constructed of a resilient plastic, suchas a semi-rigid vinyl, nylon or the like. The guide members have a crosssection illustrated best in FIG. 4, including a pair of longitudinallyextending recesses 106 and 108 for receiving the camming and lockingstructure 76. The members 18 and 20 are further provided with lesserrecesses 110 and 112 for receiving the edge portions 114 and 116 of thejambs of the sash 14 and 16, whereby the sash are guided in verticalmovement within the frame 12, as previously indicated.

The arcuate resilient portions 118, 120 and 122 of the guide members 18and 20 extend into the pockets 42 and 44, as shown, and tend to urge themembers 18 and 20 out of the pockets 42 and 44 and into engagement withthe jambs of the sash l4 and 16. The direction in which the arcuateportions 118, 120 and 122 are bent and the resiliency thereof provideweathertight window structure between the frame 12 and sash 14 and 16.

The frame portions 36 and 38 are provided with projections 124 and 126thereon extending into the pocket 42 which mate with abutments 128 and130 on the portions 118 and 120 of the guide members 18 and 20 tomaintain the guide members 18 and 20 within the pocket 42. Similarprojections 132 can be provided on the portion 40 of the frame jambs 24and 26 and on the portions 122 of the guide members 18 and 20.

Locking structure 134 is provided operable between the sashes 14 and 16in the closed position and weather-stripping 136 and 138 is provided asdesired to maintain a weathertight window.

The window structure is completed by the wood interior molding 140secured over the portions 40 and 52 of the head, jamb and sill members22, 24, 26 and 28 of the frame, as shown in FIGS. 3 and 4.

In overall operation, with the locking structure 134 unlocked, the innersash 14 may be grasped by the head and pulled inwardly to pivot aboutthe camming and lock structure 76 at the bottom thereof on forcing ofthe portion of the guide members 18 and supported primarily by theportions 122 inwardly of the pockets 44. Thus, either surface of thewindow pane 68 may be exposed on the inside of the window structure 10for cleaning or the like, as shown in FIG. 2. On lowering the upper sash16, the head of the upper sash 16 may be gripped and the upper sashpivoted about the camming and locking structure 76 adjacent the bottomthereof to urge the portion of the guide members 18 and 20 supportedprimarily by portions 118 and 120 into the pockets 42. Again then bothsurfaces of the window pane 64 in the upper sash 16 may be exposed forcleaning or the like on the inside of the window structure 10.

With the windows in the tilted position, as shown in FIG. 2, they may befurther inclined so that one side is raised higher than the other,whereby the camming and locking structure 76 may be removed from therecesses 106 and 108 and the sash 14 and 16 completely removed from thewindow structure 10 for replacing, repairing or the like.

Conversely, when it is desired to close the window structure 10, thesash are first placed in the frame 12 with the locking and cammingstructure 76 in the recesses 106 and 108 to provide a horizontal pivotaxis for the sash, and the sash is then pivoted back into the verticalposition with the guide portions 114 and 116 of the sash within therecesses and 112 of the guide members 18 and 20. The lower sash may thenbe moved all the way to the bottom, as illustrated in FIG. 3, the uppersash may be moved all the way to the top and the locking structure 76latched, whereby the bottom of the lower sash is secured due to thecamming and locking structure 76. The top of the lower sash and thebottom of the upper sash are secured due to the pivot pins adjacent thebottom of the upper sash and the latch structure 134 and the head of theupper sash is secured due to the placing of the head of the sash of thepocket 42 in the head member.

When it is desired to install two of the double hung tilting windowstructures 10 side by side, as illustrated in FIG. 10, the installationmay be rapidly accomplished in a water-tight manner by use of themullion strip 142, illustrated best in FIGS. 11 and 12. The mullionmember 142 has a cross section, as shown in FIG. 12, which is generallyH-shaped having the cross bar portion 144 and the opposite end portions146 and 148. The end portion 146 is terminated with portions extendinginwardly toward each other and terminating in points, while the endportion 148 is outwardly concave, as shown in FIG. 12.

In installation, the first window structure 10, for example the windowat the left side in FIGS. 10, 11 and 12, is installed in the usualmanner after the mounting flange 30, as shown best in FIG. 4, has beenpartly broken off. The end portion 146 of the H-shaped cross section ofthe mullion member 142 is then engaged with the remainder of themounting flange of the left window 12, as shown in FIG. 12.Subsequently, the remainder of the broken off mounting flange of theright hand window structure 10, as shown in FIG. 10, is inserted in theend portion 148 of the H-shaped cross section of the mullion member 142and the window structures 10 are urged together, while the second window10 is fixed in place.

Due to the configuration of the cross section of the I-I-shaped mullionstrip 142, including the pointed end portions 146 and the concaveoutward end portions 148 which at their closest point are closertogether than the width of the cross bar 144, the mullion strip snuglyengages both broken off mounting flanges of the windows 10 in assembly,as illustrated in FIG. 11, to provide a water-tight vertical barrier forthe window structures in side by side installation.

It will be understood that additional windows may be similarly installedand that if it is desired to install a pair or more windows at angles,such as and 45 with respect to each other, such installation can beaccomplished with mullion strips similar to mullion strip 142 and, forexample, I-shaped mullion members having the desired angle positionedbetween the windows.

In shipment of the double hung tilting window structure 10, it isparticularly desirable to maintain the frame in a predetermined relationto the sash so that when the window structure 10 is installed, theproper compression will be applied to the sash by the guide strips 18and to permit easy movement of the sash. In accordance with theinvention, the dimension between the frame 12 and the sash l4 and 16 ismaintained by the exterior packing and shipping clip 152 and theinterior packing and shipping clip 154, as shown best in FIGS. 16 and17, respectively.

The exterior packing clip 152 includes the flat portion 156 adapted toextend horizontally of the window structure illustrated in FIG. 10 inposition thereon and having the nailing opening 158 extendingtherethrough. The flat portion 160 of the clip 152 extends perpendicularto the portion 145 and is terminated in a sharp flange 162 on one side,as shown in FIG. 16.

In installation, as shown in FIG. 15, the sharp flange 162 of thepacking clip 152 is inserted in the recess 164 extending longitudinallyof the frame jambs 162 and the flat part 156 of the clip 152 is placedin surface to surface engagement with the bottom surface of the sill ofthe upper sash 16 in the upper position thereof and is secured in placeby convenient means, such as nail 166. The frame 12 is thus not allowedto bow outwardly of the sash.

The packing and shipping clip 154 includes the three relativelyperpendicularly flat portions 168, 170 and 172, connected as shown inFIG. 17. The plane 172 is substantially triangular and the plane 170includes a fastener notch 174 extending thereinto from one edge thereof.Rectilinear portion 176 extends in the plane of portions 168 and 170 ofthe clip 154 and through the plane of portion 172 thereof at theintersection of the planes, as shown. The portion 168 of the clip 154ter minates in a flange 178 extending at right angles thereto.

In use, as shown best in FIG. 14, the interior packing and shipping clip154 is positioned with the portions 168 and 170 in surface to surfaceengagement with the inside of the jamb of the sash l4 and the surface180 of the wood molding 140 with the rectilinear portion 176 positionedbewteen the jamb and molding and the flange 178 engaging the jamb, asshown in FIG. 14. The clip is then secured in place by fastening means,such as the nail 182. The sash 14 and the frame 12 are thus rigidlysecured in predetermined relation for shipment and storage to insureproper installation.
